fluke 289 problem
Ugur:
You may see different values on the card. You can put the rotary position in ACV and measure again.

and it was still the same, until i turned the switch to the Ohm menu, even to the mA / A menu.

If removing RT1 fixes it are you sure its not some kind of really high resistance short at the jacks or something? Conductive goo?
Ugur:
There is a parallel capacitance connected to it so you may measure it differently. I don't think there is a mistake but if you want to be sure you should remove it and try it.
Have you tried heating the card with a hot air station?

i haven't done that, i just cleaned with a brush, so that no dust sticks, but haven't tried heating with hot air. Maybe this is the last solution if i don't find any damage, i will try washing with alcohol and drying with hot air.
